Abstract null null Organosilane, with functional organic groups attached to inorganic silicon atoms, exhibits excellent passivation performance for pyrite. However, a considerable number of micro-cracks will gradually appear on the surface of passivation film under long-term corrosion of oxidizing medium, resulting in a significant decrease of passivation effect. To improve the stability and long-term performance of organosilane coating, a novel passivator (PT-ATP@HQ) with self-healing function ...

Abstract null null Enzymes have important advantages in sludge dewatering, but their catalytic performance is limited by their poor activity and stability. To address this issue, we develop a series of immobilized enzymes (immobilized acid protease, IE 1; immobilized pectinase, IE 2; immobilized laccase, IE 3) prepared by the electrostatic interaction between the Fe3O4@SiO2-NH2 as immobilized carrier and the free enzyme, and used for sludge dewatering. As-obtained immobilized enzymes endowed hig...

Abstract null null Hypothesis. null Organic co-solvents, which are universally employed in adsorption studies of hydrophobic organic chemicals (HOCs), can inhibit HOC adsorption by competing for active sites on the adsorbent. The adsorbent structure can influence co-solvent interference of HOC adsorption; however, this effect remains unclear, leading to an incomplete understanding of the adsorption mechanism. null null null Experiments. null In this study, dioctyl phthalate (DOP) was used to inv...

Chromium is recognized as one of the most harmful heavy metal pollutants. A facile and efficient removal technology of Cr(Ⅵ) is an urgent need, but still a challenge. Here, a novel core-shell magnetic mesoporous polydopamine nanocomposite adsorbent (Fe3O4@mesoPDA) was prepared by in-situ polymerization of dopamine on the surface of Fe3O4 nanoparticles. The adsorption of Cr(Ⅵ) was highly pH-dependent, and the optimal Cr(Ⅵ) adsorption was at pH=1.5 with the maximum adsorption capacity of 574.71 mg...

Abstract Enhancing the performance of polymer micelles by purposeful regulation of their structures is a challenging topic that receives widespread attention. In this study, we systematically conduct a comparative study between cyclic grafted copolymers with rigid and flexible rings in the self-assembly behavior via dissipative particle dynamics (DPD) simulation. With a focus on the possible stacking ways of rigid rings, we propose the energy-driven packing mechanism of cyclic grafted copolymers...

Abstract Electron transfer often drives the adsorption, but its role is difficult to determine by traditional experimental methods. In this work, two typical carbonaceous materials, graphene (GPE) and graphyne (GPY) were selected as adsorbents, and three sulfonamide antibiotics, sulfamethazine (SMT), sulfamethoxazole (SMX), and sulfamethizole (SMZ) were used as the model adsorbates. Molecular dynamics simulations and quantum chemical calculations were combined to explore the adsorption behavior ...

The science linking thermochemical conversion of large-scale industry oily sludge with applied materials has been improved in the last ten years. However, with the traditional converting methods it is hard to precisely control the composition and structure of oily sludge-based products during pyrolysis due to the complexity of the composition of the oily sludge. Here, a chlorinating calcination method using sodium chloride (NaCl) as a chlorinating salt and template was first developed to prepare...

Abstract The spontaneous gelation tendency of nanosilica sol (NSS) greatly affects its application as a raw material in chemical production. Therefore, disclosing the gelation process and mechanism of NSS plays a vital role in effectively regulating the gelation process. Herein, we bring deep insight into the gelation process of NSS which mainly includes four stages: Short silicon oxide chains (Si–O chains) are formed on the surface of nanosilica particles. Si–O chains gradually grow into the so...

Good stability and controlled drug release are important properties of polymeric micelles for drug delivery. A good candidate for drug delivery must have outstanding stability in a normal physiological environment, followed with low drug leakage and side effects. Moreover, the chemotherapeutic drug in the micellar core should also be quickly and “on-demand” released in the intracellular microenvironment at the tumor site, which is in favor of overcoming multidrug resistance (MDR) effects of tumo...

Dissipative particle dynamics (DPD) simulations were used to study the self-assembly behavior of polymer brush with rod-coil backbones polycaprolactone-b-poly(2-(dimethylamino) ethyl methacrylate)-grafted cellulose nanocrystals (CNC-g-PCL-b-PDMAEMA) and to further examine the influences of polymer concentration, rod-block proportion and distribution of backbones and the grafting density of side chains on the resulting aggregate conformations. We proposed the “rod-coil competitive mechanism” for ...
